Table 1.

A subset of the behaviors used in BigO.

Behavior	How it was computed
Average steps per hour across visits to the region	For each visit to the region, take the total number of steps during the visit, as well as the duration of the visit and compute the average steps/hour. This behavior is the average of these values across visits (even if they are visits from the same individual). For the computation of this indicator, only visits that last 1 minute or more are considered.
Average steps per hour across visitors of the region	For each unique visitor of the region, take the total number of steps during his or her visits, as well as the total time he or she spent in the region, and compute the average steps/hour. This indicator is the average of these values across unique visitors. For the computation of this indicator, only visits that last 1 minute or more are considered.
Percentage of visits to the region that include at least one visit to a food-related location	Compute the percentage of visits to the region that include at least one visit to a food-related place. For the computation of this indicator, only visits that last 1 minute or more are considered.
Percentage of visits that include at least one visit to an athletics or sports facility	For each visit to the region, take the number of visits to an athletics or sports facility. This indicator is the average across visits. For the computation of this indicator, only visits that last 10 minutes or more are considered.
Average daily number of steps for residents of the region	For each resident of the region, compute his or her steps using the recorded data across all the areas that the resident visited. Based on this, compute his or her daily average number of steps for days with more than 60 minutes of recorded data (days with fewer data points are discarded). This indicator is the average of this value across the residents of the region but corresponds to the behaviors that might have happened anywhere on the map.
